1. Toss Payment Deep Link
supertoss://send?bank=국민은행&accountNo=123456789012&amount=50000&message=결혼축하
When this link is converted to a QR, scanning it opens the Toss app with the bank, account number, amount, and memo pre-filled.
2. What if a Guest Doesn't Use Toss?
If the QR is scanned but Toss is not installed, it simply does nothing. That's why we also provide a copy-text button so guests can manually enter the account number in their own banking app.
3. How to Insert into an Invitation
- Mobile Invitation: Upload the QR PNG as an image, or insert the text into a 'View Account' button.
- Printed Invitation: Place the PNG at least 25mm wide for print.
- KakaoTalk: Copy the text and paste (share the QR image separately).
4. Privacy Tips
- Account numbers and holder names are never sent to any server — stored only in browser localStorage.
- If you publicly upload the QR on SNS, it becomes fully public. Share only within a closed group or invitation.
- Account numbers alone are difficult to misuse, but combining them with ID numbers or passwords is risky.
5. Difference from KakaoPay Transfer
KakaoPay transfers require both parties to be KakaoPay users, which limits availability. Toss uses account numbers directly, making it more universal. This tool uses Toss deep links by default.
